It boils down to giving more information to the underlying
implementation with hope that it can be useful for something. Although
at this point I think strncmp vs strcmp vs memcmp may be not worth
doing (we keep explicit length comparison to reduce *cmp calls
though). The gain is relatively small and will become even smaller
after we avoid running exclude on tracked files (which eliminates like
2/3 of the processed entries).
